Main Panel Upgrades

Signs You May Need a Panel Upgrade

Your panel is a brand with known problems. Zinsco and Federal Pacific (FPE) panels are no longer UL listed and are no longer approved by local jurisdictions. These panels have a documented history of breakers that fail to trip during overloads — which means the protection they’re supposed to provide doesn’t work. If your home has either of these brands, replacement is not optional; it’s a safety issue.

Your panel is 100 amps (or less). 100-amp service was the standard for residential construction through much of the 1980s. It’s insufficient for a modern home running air conditioning, multiple large appliances, an EV charger, and the rest of a contemporary household’s electrical load. Most homes today need 200-amp service minimum.

Breakers trip frequently. A breaker that trips is doing its job. Abreaker that trips repeatedly on the same circuit is telling you that circuit is overloaded, which often means the panel as a whole is at or beyond its capacity.

You want to add an EV charger, solar, or a major appliance. A 50amp EV charger circuit, a solar system’s back-feed breaker, or a new electric appliance may not fit in your current panel, either because there are no open slots or because the panel’s total capacity is already being used. We assess this before quoting any of these additions.

You’re selling your home. Buyers’ inspectors flag outdated panels. An aging panel especially Zinsco, FPE, or an older 100-amp box can kill a sale, or require a credit at closing. Upgrading before listing is often the cleaner path.

You’re preparing for solar. Solar installers require specific breaker space, correct busbar capacity, and in some cases a full panel replacement as a prerequisite. Having the panel right before the solar crew arrives avoids delays and additional costs.

You’re adding a room or remodeling. A room addition or major remodel often triggers an electrical inspection — and inspectors will flag an undersized or outdated panel as part of that process. Beyond the permit requirement, a remodel is also the most practical time to upgrade the panel, while trades are already on-site and the project is already disrupting the home. Doing it during a remodel costs less and causes less disruption than returning to do it separately later.
